In Climbing Mount Improbable, Richard Dawkins, author of The God Delusion, builds a powerful and carefully reasoned argument for evolutionary adaptation as the force behind all life on earth. What drives species to evolve? How can intricate structures such as the human eye, the spider's web or the wings of birds develop, seemingly by chance? Regarding evolution's most complex achievements as peaks on a metaphorical mountain, Climbing Mount Improbable reveals the ways in which the theory of natural selection can precisely explain the beautiful, bizarre and seemingly 'designed' complexity of living things. And through it all runs the thread of DNA, the molecule of life, responsible for its own destiny on an unending pilgrimage through time. Accompanied by evocative illustrations, Dawkins's eloquent descriptions of the living world's astonishing adaptations throw back the curtain on the mysteries of 'Mount Improbable'.
